I know exactly what you mean. I'm not sure how to do it though and was curious about this myself, any electricians here? Do you wire them in "series" or "parallel"? How many amps do they draw? And how many could you wire into a single line, ect.?
i went to walmart and bought a 3 light bathroom fixture for $8. then went to home depot and got 3 y extensions and ended up with 6 lights. it already came prewired and i believe it handles up to 300 watts.
